Use of different calcium ions added in the extender of swine cooled semen
Keywords:
Sperm, calcium, motility, boar semenAbstract
Studies show that calcium ion is very important for the regulation of sperm motility. Thus the objective was to assess the quality of sperm swine flu under the effect of different types and concentrations of calcium ions in the BTS. The semen of boars was collected and analyzed for their parameters. The experiment included the use of different types of calcium diluted in BTS: calcium carbonate, calcium hydroxide, calcium phosphate dibasic anhydrous, hydrated calcium sulphate, anhydrous calcium sulphate, added to the BTS extender in different concentrations: 0 mM (control); 0.4 mM; 4 mM; 40mm and 400 mM. After collecting and seminal review, the samples were diluted and stored at 17 oC. To evaluate the effect of calcium was removed from an aliquot of each sample, which was subjected to a temperature of 37 °C for vigor, vitality and sperm motility, performed on D0, D2 and D4. The addition of calcium salts provides the sperm hyperactivation, and as a sperm membrane and acrosome membrane, these salts in their levels mentioned above did not exert a negative effect.
